Asus has launched its Transformer Book TX300 in India. It is the thinnest Windows 8 tablet in world with 13.3 inch full HD IPS display and is powered by Core i5 3337U processor, which powers most of the ultrabooks out there.
Asus S551 is a 15.6 inch ultrabook that features new Haswell processors by Intel. Like its predecessor, Asus S550CM, it also comes with discrete Nvidia GeForce GT 740 GPU. Battery life is said to be around 6 hours on a single charge. It is mere 0.88 inches thick and weighs about 2.4 kilograms.
Asus Taichi 31 is first true ultrabook that sports 2x 13.3 inch IPS panels. As it has 2 screens, it allows the user to use it as tablet when the lid is closed. Thus, there is no need for a rotating hinge. The Taichi 31 features about 7 ours of continuous runtime on a single charge, which pretty amazing for a laptop with 2 screens.
If you cannot live without an optical drive, Asus S550CM might just fit the bill. S550CM features 15.6 inch HD screen that is backed by Nvidia 635M GPU and Core i5 processor.
